DIGITAL WEATHER FORECASTER
WITH HYGROMETER AND
RF CLOCK
MODEL : IBR923 DECO-BAR
USER'S MANUAL
INTRODUCTION
Congratulations on your purchase of the IBR923 Digital Weather
Forecaster with Hygrometer and RF Clock. The IBR923 is an all-in-one
weather forecasting device and clock.
The IBR923, a weather forecasting device, has several weather
related functions. A main feature is that it takes and records
temperatures in more than one location. Using a wireless remote
thermo-sensor, it can simultaneously monitor temperatures in
three remote locations. The unit will show temperature trends and
record maximum and minimum temperature readings.
As part of the weather forecasting function, a built-in barometer that
displays atmospheric pressure. Using graphic illustrations the unit
displays atmospheric pressure trends and displays forecasts as
sunny, partly cloudy, cloudy, and rainy.
The IBR923 is also a Radio Frequency (RF) controlled clock. It can
automatically synchronize its current time and date when it is
brought within an approximate 1500 km radius of the radio signal
generated from Frankfurt, Germany (DCF77).
Included with this unit is a hygrometer. This feature graphically
illustrates the current comfort level, displays the current humidity,
and shows maximum and minimum humidity levels.
Other features include extra-large liquid crystal display (LCD), and
a daily crescendo alarm.
No wire installation is required between the main and remote units
as the IBR923 operates at 433 MHz.

Note: For both the remote sensor and the main unit, replace batteries
when they are low. The [ ] battery low indicator in the outdoor
temperature window will be displayed when the batteries are low.
ABOUT RADIO RECEPTION
The IBR923 is designed to automatically synchronize its calendar
clock once it is brought within range of the Frankfurt DCF77 radio
signal. It will scan and adjust every full hour.
When the unit is within range, its radio-control mechanism will
override all manual settings.
When the unit is receiving radio signal, the RADIO RECEPTION
signal will start to blink. A complete reception generally takes about
two to 10 minutes, depending on the strength of the radio signal.

CHECKING INDOOR AND REMOTE
SENSOR TEMPERATURES
The indoor temperature readings, and indoor temperature
maximum/minimum indicator are all part of the INDOOR
TEMPERATURE window.
The OUTDOOR temperature window displays remote sensor
temperatures, maximum and minimum temperatures and outdoor
temperature trends. This window also displays the remote sensor
channels and a remote sensor battery low [ ] icon.
The temperature can be shown in Centigrade (˚C) or Fahrenheit (˚F).
Select the appropriate reading by using the ˚C/˚F slide switch. Slide
the switch to ˚C for Centigrade or ˚F for Fahrenheit.
NOTE ON OUTDOOR-REMOTE TEMPERATURE
Once batteries are in place in the remote unit, it will start transmitting
samplings at 30 second intervals.
If no signals are received when the outdoor-remote temperature is
selected, “ ” will be displayed. To force the main unit to search
for remote sensor signals, press MEM and CHANNEL
simultaneously.
If that fails, check that the remote sensor is still in place. Make sure
the transmission is within range and the path is clear of obstacles and
interference.
Repeat this procedure whenever you find discrepancies between the
display on the main unit and the display on the remote sensor.

WEATHER FORECAST
The unit is capable of detecting atmospheric pressure changes.
Based on collected data, it can predict the weather for the forthcoming
12 to 24 hours. The effective range covers an area of 30 to 50 km.

NOTE:
1. It is not necessary and not possible to adjust the altitude of the
weather station. After the initial start-up of the weather station, a
first forecast will be made within the first 24 hours of operation.
2. In periods of long stable weather conditions, it becomes difficult
to make a reliable forecast.

IBR923os-tech_ENoutput 04/25/2005, 11:339
EN
3. The weather forecast is solely calculated on the basis of barometric
air pressure changes.
4. The probability of a correct weather forecast is approximately
70% and is valid for an area of approx. 20-30 km around the
location of the weather station.
5. The forecast “Sunny” means at night “cloudless weather”. Fog is
not indicated by the weather station as this can occur with
different weather conditions.
6. If you travel with the weather station, a reliable weather forecast will
become impossible due to changes in altitude and location. You’ll
have to wait up to 24 hours so that the weather station can calculate
a new forecast based on the conditions at the new location.
HOW TO USE THE RELATIVE HUMIDITY
The relative humidity is displayed as a percent. The corresponding
“happy face” illustration graphically illustrates the level of
humidity as comfortable, wet, or dry.
HOW TO WALL MOUNT OR USE THE
TABLE STAND (REMOTE UNIT)
The unit can be wall-mounted using its recessed screw holes or place
on a flat surface using the table stand.
